Help with AutoCAD LT 2021

[rogantano09]

At my workplace we do simple line drawings of carriage doors. We just recently went from the 2013 version to LT 2021 and I can't get a couple of tools to work correctly.

Before we used the Multi-line tool to draw mullions to separate the different lites in the windows. Now I'm trying to use the Double line tool, but can't get it to draw anything aside from a set of lines that are just 1/16" apart. I've tried changing the size, but I can't get it to do anything different.

The other tool that I'm having issues with is the Stretch tool. In the 2021 version it seems to only want to move one or two lines that are parallel to each other but not the other lines intersect them, in this case vertical T&G.

Any help with this would be greatly appreciated. Google has given me steps to follow but they didn't work or else I wouldn't be here, haha.  https://9apps.ooo/

I can't help with your stretch tool. I only have LT 2016, however DLINE has not changed, after starting the command press W for Width. See the image below

MLINE is unique to full AutoCAD: there is no comparable tool in the LT versions of AutoCAD, sorry.
DLINE stands for DoubleLINES and all it can do in two lines, with limitations, and none of the MLINE customizations you are used to using.

Not sure I follow the STRETCH command issue though: except for the fact that DLINEs do not behave line MLINEs, there is literally no difference in usage of STRETCH in full AutoCAD nor LT regardless of year version. Perhaps some visuals from you can help?
